Experimental details: Non-transfected (¡V) and transfected (+) 293T whole cell extracts (60 ?g) were separated by 5% SDS-PAGE, and the membrane was blotted with BRCA1 antibody [6B4] - ChIP grade (GTX70115) diluted at 1:500. The HRP-conjugated anti-mouse IgG antibody (GTX213111-01) was used to detect the primary antibody.

Experimental details: BRCA1 antibody 6B4 (GTX70115) was used for western blot assay at 1:1000 antibody dilution. western blot assay was performed using MCF7 (human) and MEF(mouse embryonic fibroblast) cell lysate separated in a 5-15% gradient gel.Observed molecular weight of BRCA1: 220 KD.Predicted molecular weight of BRCA1: 220 KD. The HRP-conjugated anti-mouse IgG antibody (GTX213111-01) was used to detect the primary antibody.

Experimental details: BRCA1 antibody [6B4] (GTX70115) was used at 1:1000 dilution for western blot assay of lysates from cells transfected with control or BRCA1-specific siRNA. Lysates were prepared at the indicated times following transfection. RAD50 antibody [13B3] (GTX70228) was used as a loading control.

Experimental details: BRCA1 antibody detects BRCA1 protein by western blot analysis. Whole cell extracts (30 and 50 ?g) was separated by 5% SDS-PAGE, and the membrane was blotted with BRCA1 antibody (GTX70115) at a dilution of 1:500. The HRP-conjugated anti-mouse IgG antibody (GTX213111-01) was used to detect the primary antibody.

Experimental details: BRCA1 antibody 6B4 (GTX70115) was used for immunofluorescent staining of BRCA1 nuclear foci induced by ionizing radiation. IR-treated (2 hr /4 gray IR) U2OS cells were pre-extracted with CSK buffer on ice for 4 min before fixation with 4% PFA in room temperature, and then subjected to immunostaining. DAPI was used to counterstain nucleus. 6B4 was used at 1:400 dilution. Secondary antibody (Alexa Fluor-488) used for detection of primary antibody (BRCA1 antibody 6B4).

Experimental details: BRCA1 antibody 6B4 (GTX70115) and BRCA1 antibody 17F8 (GTX70111) was used for IP-WB assay. 6B4 alone (4 microgram), 17F8 alone (4 microgram), 6B4 plus 17F8 (2 microgram each), and mouse control normal IgG were used in an immunoprecipitation assay with MCF7 cell extract. Immunoprecipitated BRCA1 was detected in WB using BRCA1 antibody 6B4 at 1:1000 dilution.

Experimental details: BRCA1 antibody 6B4 (GTX70115) and BRCA1 antibody 17F8 (GTX70111) were used for ChIP assay. The 6B4 and 17F8 mixture (3 microgram each), or normal mouse IgG (6 microgram) were incubated with HeLa chromatin extract (100 microgram each) in the ChIP assay. Enrichment of genomic DNA on a BRCA1 target gene promoter (HMGA2) was validated by a Q-PCR assay.
